99base/init: predefine path to init
if you add realinitpath="<path1> <path2>" to dracut.conf, then it will
be written to $initdir/etc/cmdline.d/distroinit.conf with

99base/init, when it searches for init.

auto setup network without netroot
Current dracut network only will be setup when netroot is used. But there are
some cases we need network even without netroot. For example kdump will need
copy vmcore to remote machine via scp or nfs mount. OTOH, if we use dracut as
a recovery system the network is helpful even root is not a network device.
This implementation is based on the manually bring up method. Here add a kernel
cmdline argument rd.neednet. If rd.neednet is set dracut will bring up network
with ifup $INTERFACE -m. If netroot is used we still keep original behavior.

allow ifup bring up network manually even without netroot
For kdump we need scp vmcore to remote machine, the nic to be used is
not limited to netroot one. we need a feature for manually bringing up
network interface. Also it is useful for emergency shell with
ssh-client for recovery or test purpose
I implement this by adding one argument to ifup script, user can use
`/sbin/ifup eth0 -m` to bring up eth0, note ifup will regard it a
manual operation for the nic specified in 1st argument if there's
the 2nd argument.
If same nic is used for netroot the 2nd argument will be ignored,
in this case we will leave netroot bring up it automatically to
avoid side effect. And in this case hooks such as kdump will need to
execute after netroot mounted.
`ifup eth0 -m` will create /tmp/net.eth0.manualup stamp file,
later dhclient-script can check this and pass $2 to netroot,
then netroot script will bring eth0 up
Thanks for comments and suggestions from David Dillow.

network/dhclient-script: set FQDN
When booting with nfsroot, dracut doesn't necessarily set the initial
hostname correctly.
According to dhcp-options(5), the name may or may not be qualified with
the local domain. It goes on to say "it is preferable to use the
domain-name option to specify the domain name".
So dhclient-script needs to be able to handle the cases: a) where
host-name is fully qualified and domain name is also specified; b)
where hostname is fully qualified and the domain is not separately
specified; c) where host-name is "short" and domain-name is also
specified; and d) do its best where host-name is short but domain-name
is not specified.
The dhclient-script in initramfs does not handle case "c", apparently
the preferred situation properly, setting hostname to "short".

Add ssh client module code
Add ssh client module which support ssh key mode and interactive mode.
with --sshkey option you can provide the ssh key to be installed

ssh-client is better, maybe future there will be ssh-server come in.
In debian these are also two different packages.
Usage:
1. sshkey mode:
transfer your public key to remote machine with ssh-copy-id or do it mannaully
example of options:
./dracut -l -H -a ssh-client --sshkey /root/.ssh/id_rsa i.img
2. interactive mode:
need use --ctty option, ie.:
./dracut -l -H -a ssh-client --ctty i.img

Add job control support to emergency shell
Option --ctty will optionally add setsid binary to dracut's image.
During runtime, if rd.ctty is set and is a character device,
emergency shells will be spawned with job control.
in case no ctty was provided, shell was spawned without caring about
/dev/console. Also, the ctty is more opportunistic. If the image was
generated with --ctty, we will fallback to /dev/tty1 if rc.ctty is
invalid or missing. Otherwise we spawn standard shell on /dev/console

init: Fix bogus message about invalid root device.
When the initqueue cannot be processed, it might be about an invalid
root device (in which case a separate message produced via
wait_for_dev() should be displayed anyway), but it could also
be for any other reason (e.g. /dev/resume not existing).
Therefore, it is best to use a more generic error message.
Also a minor tab->space conversion in the near vacinity of
the real change.

resume: Fix failure when invalid device passed via 'resume='
This commit allows the waiting for a device to be cancelled.
When the resume partition does not exist, it becomes quite hard
to work out what to do (you have to either create the
/dev/resume symlink manually, or remove the 'finished' job
that is waiting for it). Additionally dracut incorrectly
displays a message about not being able to find the root
device, which is bogus and misleading.
This commit should just bail on the whole resume thing
if the device cannot be found and proceed with a normal boot.
